[comp.sys.sun] Audio on SPARCstation

edmund@uunet.uu.net (Edmund lai) (01/04/90)

What is the data format for the audio device on the SPARCstation?  I have
tried straight binary and offset binary (most significant bit being the
sign bit).  But they don't seem to be correct.  Any information would be
helpful.  Thanks.

The SS1 audio is in uLAW (really Mu-LAW) format.  It is a method of
compressing analog waveforms into 8-bit samples.  I previously posted a
program to convert MAC style files (excess-128 samples) into uLAW format
for the SS1.  It's called sound2sun, and is available from the Rice
archive server.
